TSXV: STAR

DRILLING COMMENCED AT

MARAVILHA DIAMOND PROJECT

Toronto, ON - Five Star Diamonds Limited (TSXV: STAR) (the

“Company” or “Five Star Diamonds”) is very pleased to announce

that the Company has commenced drilling at its Maravilha

Diamond Project (“the Project”), located in Brazil.

The focus of the drilling programme is on the companies 100%

owned M3 kimberlite pipe where bulk sampling has returned

exceptional early sampling results.

The drilling program will utilize two drill rigs working on a single

daily shift. Approximately 3,200 meters of diamond core drilling,

distributed across approximately 30 drill holes, is planned in the

programme. All drill holes will be drilled using a HQ (63.5mm)

diameter to provide ample material for further diamond sampling

and analysis.

Core logging and recovery rates are being conducted by Five Star

field crew. The core is also being submitted to magnetic

susceptibility readings and chemical assays. All the core is being

photographed and a drilling database is being constructed to

enhance additional geological modelling

Previous interpretation of a ground magnetic survey undertaken by

the Company shows that the M3 kimberlite pipe has a strong

magnetic response suggesting an ovoid shape measuring

approximately 130 by 65 meters with the major axis aligned along a

northeast to southwest direction.

The Company also previously announced exceptional early results

from an initial bulk sampling program to test the M3 kimberlite pipe.

A total of 658 macro and microdiamonds were recovered in the

program.

Next Steps

The Maravilha Diamond Project comprises three mineral properties covering a total of

1,233.17 hectares and the Company is conducting a systematic exploration program,

including detailed ground magnetic survey and auger drilling, with the aim of identifying

additional kimberlites bodies in the Project.

As soon as the drilling program is completed on the Maravilha Diamond Project, the drill

rigs will be mobilized to commence a new drilling program on the Company’s Catalao

Diamond Project, located in Goias State, Brazil.
